IMPROVEMENT iN SPRING BED-aoTroMs.

The Schedule refezred to in' these Letters Patent and making part of the same.

Be it known that I,ALEXANDER COLE, of Manamuskin, in the countyofGumberland and State of .New Jersey, Vhave invented certain Improvements in p Spring Bed-Bottomsrandll do hereby declare that the following, taken' in connection with 4the drawing p which accompanies and forms part of this speciflca- A tion, is a description of my invention `abile those skilled in the 'art to practice it.`

suiiicient to er1-- My invention is an improvement on my patent No.

56,37 3, and the` novel features relate to certain details of construction hereinafter fully described. p 4 Figure 1 is alougtudinal section of a bedstead having my improvements thereon Fiuure', aotosssection` the feature re resented in c r. p

Iig.`3 being,r shown inonly one of the springs; Figure `3, a detail `view; and i i fFigure 4, a` plan` View ofpone of` the longitudinal A is a board for sustaining the rods and springs 1 hereinafter..mentioned, of snflcient breadth for that purpose, and of a length suclras `to reach across the bedstead, one being used for` the head'and one for the To thisboarfhat its, bottom,`I attach, by screws or otherwise, astrip, as` shown, having a series of holes toreceive the lower ends of a series of wire rods, C, the 4,upper bent ends of such wires being bent from a vertical `to a horizontal position, and the ends of their hori zontal parts entering corresponding holes inthe board i A, as shown. p

The part composed ofAand` B I attach to the head 'and foot-rails of any commonl bedsteaihby scfeivs or t otherwise, and'it may thus bereadiIy applied or removed,Wheneverdesiredfor any purpose. It may, be applied to other parts than the rail, dependent upon the particular construction of the `bedstead.

" jAround each guide-rod or wire O I place `a coiled spring, resting at `its lower end upon the part B, and more particularly.,described hereafter. ,t

E E, 811e., are longitudinal strips of Wood, each having at both ends au open-ended `so that its slotted-.endshall span 4the'wirerod, and

p, `also admit of its being as readily removed for any purpose; or `when it is `broken that another may vre- `place it. Y

The slots e extendjustfarl enough from the end of `chaling against the `board `A,`,the wire rod serving to ,j limit` its end play, and torho'ld it steady against too i M much movement and consequent'noise.

`The series of slats being placed as shown, each above the coiled springs, a steadying-strip, F, is next introp slotonnotch, e, as shown, which admits ofits being readily put to place,-

the slat to prevent-such end fromwever reaching to and duced beneath the bent top of the wire rods and the slats, as shown. This strip F may be'made of wood, band-iron, wire, twine, leather, or other appropriate material, which will serve to arrest, equalize, and steady the slats in their upward Imovements under the pressure of their springs.

When, however, 4iiexible material is used instead of the rigid strips, I tie or secure its ends to hooks or` staples G, which may-be inserted in the siderails or at any convenient place in the bedstead.

H is a conical' plug or washer, of wood, adapted tov lie within the upper half of each spiral spring, such upper half being preferably', for that purpose, coiled-to a somewhat conical 'or tapering shape from the top. The washersrare bored that they may be placed upon the guide-rods, and'with their larger ends upward; they are thus held to place by the tapering coil and the rod, but are yetA perfectly free in the movements of the spring, under pressure or recoil, to move with Vi1 without getting displaced. VThese washers thus serve to prevent the spiral springs from chaling the guiderods, and hence to prevent all unpleasant noise arising therefrom. They also serve to steady the spring, and contribute largely toward keeping it--in proper shape I and consequent eiiciency.

AThe guide-rods areA preferably made of rod-iron of about a quarter of an inch in diameter, and of about six inches in' length in the vertical part and two inches in the horizontal part outside the wood. This horizontal part, it will be seen, acts of itself as a stop to the upward vmovement of all the other parts whichare upon the rods, and I am thus enabled to dispense with ,a specialxed cap-piece at the top of the rods, such .as is shown in my patent above referred to, and which would not admit'of taking the bedstead apart, as I can do in my present construction.

I alsodispense with the metallic hangers shown in said patent as attached to the ends of each slat.

The ,spiral springs* may be made of brass or steel wire, and about four and one-half inches in length of coil when not compressed.

' The slats I make about, five-eighths of an linch thick and about 'two inches wide.

The prominent advantages of my present improvements are, the very slight liability to get out of order;

the simplicity, durability, and cheapness of the construction; the facility with which they can be applied to an ordinary bedstead, and by any person of ordinary skill; and the ease with which the whole can be taken. apart and repaired in case any part becomes l broken or lout* of order, or with which a slat can be ,replacedor reversed, or any two of them may change places without rem'oving any'other part.

'I claim- 1, `The A combination of the vertical strip A, having tot ttm,

horizontal part of the guide-rods, as and for the purpose described.

4. The combination, with the bent-Wire rods G, and

with the spiral springs, tapering from the top toward the middle, of the tubular conical pieces H, as and for the purpose set forth.
